Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] As shown in Figures 1 to 3, the miniature vacuum valve for flywheel of the present invention is mainly composed of an air extraction interface 1, a first O-ring 2, a valve body 3, a valve core 4, and a second O-ring 5. Among them, the valve body 3 is a part of the vacuum chamber of the flywheel, and the rotation of the vacuum chamber makes the valve body 3 rotate. The cooperation between the valve core 4 and the valve body 3, and the cooperation between the valve core 4 and the suction port 1 are all threaded connections. 4 is a double-thread structure, the outer thread and the inner thread have the same direction of rotation, pitch and lead, and the second O-ring 5 is used for sealing. The air extraction interface 1 is a piston structure, and the first O-ring 2 is used for sealing seal.

Abstract

The invention relates to the technical field of vacuum valves, in particular to a miniature vacuum valve for a flywheel. The miniature vacuum valve comprises an exhaust connector (1), a first O-shaped sealing ring (2), a valve body (3), a valve element (4) and a second O-shaped sealing ring (5). The valve body (3) is a part of a flywheel vacuum cavity, and the vacuum cavity is rotated to enable the valve body (3) to rotate; the valve element (4) is of a double-thread structure, and an external thread and an internal thread are identical in screw direction, pitch and lead; the valve element (4) is matched with the valve body (3) in a threaded connection mode, and the valve element (4) and the exhaust connector (1) are matched in a threaded connection mode; and the exhaust connector (1) is of a piston type structure and sealed by the first O-shaped sealing ring (2). The miniature vacuum valve has the characteristics of being small in size, simple in structure, convenient to use and low in weight; the weight of a flywheel product is reduced, the requirement of a miniature flywheel product for a small vacuum valve is met, and after the valve is closed after vacuumizing, the exhaust connector can be dismounted, so that attractiveness is not affected.

Description

technical field [0001] The invention belongs to the technical field of vacuum valves, in particular to a miniature vacuum valve for flywheels. Background technique [0002] In the attitude adjustment and energy storage flywheel research, the flywheel needs to work in a high vacuum environment. At present, domestic and foreign flywheel products generally use a flange joint to weld a section of oxygen-free copper tube and seal it with glue to vacuumize and seal the cavity. One end of the oxygen-free copper tube is welded and connected to the vacuum pump pipe, and the vacuum is pumped through the oxygen-free copper tube. When the vacuum degree of the flywheel vacuum chamber reaches the standard, the end of the oxygen-free copper tube is crushed and stuck with a special caliper, and then cut off and welded immediately. , the truncated copper tube is left on the flywheel cavity as a seal, so as to meet the sealing requirements after the vacuum degree reaches the standard. When ...
